Further to the above, I think I got around the problem by doing
'mknod /dev/hda7 b 3 7'.
I then had a problem with /dev/null, but I seem to have got round that
with 'rm /dev/null' which then allows grub to recreate it.
I say "think" and "seem" because I'm not sure if it has really worked
yet. That is because I am now getting an error message: "The file /
boot/grub/stage1 not read correctly." That has me really stumped!
Any ideas? I really want my Ubuntu back!
